Answer:
B
Explanation:
the number of protons never changes even if the atomic mass changes
This is an example of Innovation.
<h3>What is an
Innovation?</h3>
Innovation is the application of concepts in a way that results in the creation of new products or services or enhances the provision of existing ones. Innovation is defined as "a new or altered entity realizing or dispersing value" by ISO TC 279 in the standard ISO 56000:2020. Others have different definitions, but they all place an emphasis on the novelty, development, and dissemination of concepts or technologies.
The creation of more efficient goods, procedures, services, technology, works of art, or business models, which innovators then make available to consumers, governments, and society as a whole, is a common way that innovation occurs. Innovation and invention are not the same thing, but they are related.

Answer:
<h2>Molarity = 7 mol / L</h2>
Explanation:
Since the mass of NaCl and it's volume has been given we can find the molarity by using the formula
<h3>
</h3>
where
C is the molarity
m is the mass
M is the molar mass
v is the volume
From the question
v = 0.5 L
m = 205 g
We must first find the molar mass and then substitute the values into the above formula
M( Na) = 23 , M( Cl) = 35.5
Molar mass of NaCl = 23 + 35.5 =
58.5 g/mol
So the molarity of NaCl is
C = 7.00854
We have the final answer as
<h3>Molarity = 7 mol / L</h3>
Hope this helps you
It is an alpha decay because when this phenomena occurs an atomic nucleus emits an alpha particle (helium nucleus) and consequentially decays into another atom with a mass number that is reduced by four an atomic number that is reduced by 2 two. The helium atom consists of two protons and two neutrons.
Therefore, the answer is <span>alpha decay because alpha particles have two protons and two neutrons</span>
A single molecule of hemoglobin can bind to 4 molecules of oxygen gas. However, hemoglobin has a greater affinity for carbon monoxide than oxygen. Therefore, an excess of carbon monoxide in the presence of oxygenated hemoglobin will result in the displacement of each oxygen atom for a carbon monoxide atom.
Hb(O2)4 (aq) + 4 CO(g) --> Hb(CO)4 (aq) + 4 O2(g)
With an excess of carbon monoxide, it is safe to assume that each oxygen molecule will be displaced with a carbon monoxide molecule. Therefore, if we have 4.5 moles of oxygenated hemoglobin (Hb(O2)4), all 4.5 moles of the species will release oxygen and bind to carbon monoxide.
